ATTACHMENT FOR LANTERNS.

Specification of Letters Patent.

Application filed March 21, 1908.

Patented Feb. 2, 1909.

Serial No. 422,606.

To all who 1., tt may concern:

Be it known that I, ORVA A. WILLETT, citizen of the United States,residing at Wellington, in the county of Sumner and State of Kansas,have invented certain new and useful Improvements in Attachments forLanterns, of which the following is a specification.

This invention contemplates certain new and useful in'iprovements inlanterns, and the object of the invention is an improved lanternattachment which is designed to be operated by the user to cause thelantern to emit a colored light when desired, and which is thusparticularly adapted for signaling purposes or the like, since thesignalman can use the same lantern to display a colored or 1 whitelight, according as required.

With this and other objects in view, that will more fully appear-as thedescription 'proceeds,the invention consists in certain constructionsand arrangements of the parts that I shall hereinafter fully describeand then point out the novel features thereof in the appended claims.

For a full understanding of the invention and the merits thereof, and toacquire a knowledge of the details of construction,

reference is to be had to the following description and which:

Figure 1 is a side elevation with parts in section, of a lantern showingmy improved signaling attachment applied thereto; Fig.2 is a detail viewin section, showing the shade in raised position; and, Fig. 3 is asimilar View in perspective, of the holder and the accompanying drawing,in

' adjusting rod.

Corresponding and like parts are referred to in the followingdescription, and indicated in all the views of the drawing, by the samereference characters.

This invention is designed to be applied to a lantern A, which may be ofany desired construction or design, exccptthat it em bodies a preferablycolorless chimney B and a crown plate C secured across the upper endthereof, said crown plate being formed with an aperture D extendingtherethrough.

My improved lantern attachment embodies a preferably cylindricalefrtensible tube that is constructed in telescopic sections. one ofsa idsections 1 being relatively stationary and constructed ,of any suitableopaque substance. This section 1 is formed at its upper end with anoutstanding flange than the section 1, and is about the same length asthe latter, said section being arranged to ext end around the flame whenthe tube extended, and being constructed of a translucent substance, soas to form a shade 3 adapted to intercept the rays of light and modifythe same in color. The shade 3 isprovided at its upper end with 2!preferably metallic collar 4.,- and its lower end rests against anannular holder 5, and fits in a cupped rim 6 formed at the upper edge ofthe letter, said holder resting against the body portion of the lantern,when the tube is in extended position, and being formed with notches 7extending therethrough to admit air to the burner.

A spring, adjusting rod 8 is secured at its" lower end to the holder 5,and extends u wardly therefrom through the aperture 5 1n the crownplategsaid rod being formed near its upperend and near its middle withcrinips i) and 9 respectively. This rod bears against the outer wall ofthe aperture 1), and the crimp 9 at the up er and of the rod is arrangedto be pushe downwardly through the ap rture D of the crown plate, whenthe shade is lowered into an operative'position, and is adapted to bearagainst the crown plate to prevent the rod from sliding; through theaperture therein, to permit the shade to accidentally return to aninoperative position during the swinging of the lantern. Theintermediate crimp 9 of the rod is arranged to he passed upwardlythrough the aperture I), when the shade is raised to an inoperativeposition and the tube tclcscoped, and is designed to abut against thecrown plate, to suspend the shade securely in such raised position.

It will be noted that the upper or relatively stationary scctirm 1 ofthe tube, will protect the chimney 1-3 of the lantern from smoke andheat, when my improved attachment is not in use. i

It is to be understood that theiadj usting rod 8 may extend throughthe'lowerend of the lantern, in case it is more convenient to operatethe shade ffom the bottom.

From the above description. in connection with theaccompapying drawing,it will be ap mrcnt that I have provided a simple, du-

rahle and ethcient lantern attachment which may be readily operated topositively con trol the color of the light emitted from the lantern.which may he applied to all lanterns ot' the m's'linary type, and whichmay be easily and cheaply n'ninn'l'actured and its parts readilyassembled.

Hm in; thus described the invention, what i 1 claim is:

1. lhe combination with a lantern having a chimney and a crown plate, ofan extensible tube constructed in telescoping sections, one of saidsections being secured to and do pending from the crown plate, and the.other section forming a shade, when the tube is extended, and a holderin which thelower end of the shade tits and which is arranged to bearagainst the body portion. of the font around the burner, said holderbeing pro- \ided with means for admitting air to the burner, as and forthe purpose specified.

The combination with a lanteri'i having a chimney and a crown plate, ofan extensiole tube constructed in telescoping sections,

'- one of said sections being secured to and depending from said crownplate and the other section forming a shade, when the tube is extended,an annular holder'formed at its u per edge with a cupped run 111 which te lower end of the shade tits, said holder being 30 formed at its loweredge with a notch exlending therethrough, as and for the purposespecified.

3. The combination with a lantern having a chimney and a crown plate, ofan extensible tube constructed in telescoping sections, one of saidsections being secured to and de 1 pending from the crown plate, and theother section forininaia shade adapted to intercept
